I'm trying to have my apps sync their database with drive so that the app data is n'sync throughout all his devices. I did some research and found this quickstart, Dr.Edit but when I downloaded the source code for a closer inspection I realised it's for 4.1+. Surprised, I checked the google drive app on google play and found out you can install it on 2.1+.

I understand that later versions of android OS not only work better but make our work as developer easier. However I am surprised I cannot find much about integrating google drive with older versions. If we check the current distribution of android versions, we can easily notice that 2.3.X alone is almost on 50% of the devices out there, so why not supporting them with our apps?

Does anyone know where to find code samples/tutorials on integrating google drive with an app written for 2.1+? I just want to sync some data (mostly the app's local database).

it says For earlier Android versions: Long-press an empty spot on your Home screen, and tap Widgets in the pop-up menu. Swipe left or right to find the Drive widget, tap it with your finger, and click Select.
